DEVICE roe REMETALING GROSS-HEADS.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed May 27, 1910. Serial N 0. 563,716.

To all whom it may concern:

Be it known that I, ALBERT AsHwoR'rH, a citizen of the United States, residing at Chattanooga, county of Hamilton, and State of Tennessee, have invented certain new and useful Improvements in Devices for Remetaling Gross-Heads, of which the following is a specification. I

My invention relates to the remetaling of engine cross-heads, and particularly to improved devices to be used in remetaling th same.

The object of my invention is to provide improved means for remetaling cross-heads which shall lessen the cost, time and labor incident thereto, and whereby the cross-head shall be ready to be replaced in position for use as soon as the metal is cool.

A further object of my invention is to provide a device for the purpose mentioned which shall be of simple construction and easy to operate.

Other objects will appear hereinafter. With these objects in view my invention consists generally in a device adapted to be arranged in the guide ways or grooves in the cross-head and adjustable in width to fit snugly therein, at a short distance fromv the inner face on the bottom of 't-he'groove,

My invention further consists in a pair of devices and spacing member as mentioned in combination with means for properly center ing the cross-head to be met-tiled"between the same.

My invention further consists in various details of construction and arrangements of parts all as will be fully described hereinafter and particularly pointed out in the claims.

My invention will be more readily underafter.

V stood by reference to the accompanying drawings forming a part of this specification and in whie Figure 1 is a side elevation of a device embodying my invention in its preferred form and illustrating a cross-head in position to be remetaled, Fig. 2 is a side elevation of the same, Fig. 3 is a horizontal section on the line 0aw of Fig. 1, Fig. 4 is a top plan view of one of the adjustable'de vices, and *ig. 5 is a detail side view of the upper end of the device illustrated upon an enlarged scale and partially in section.

In carrying out my lnventaon I provide a pair of parallel bars rigidly connertedat one end. The opposite ends of the bars are adjustable in. width and. are provided with means whereby the adjustment may be readily made.

Referring now to the drawings 1l indicate the parallel bars and 2 a member interposed between the ends thereof at one end and to which they are secured. In practice I prefer that the memberfl be a cross-headv to which the. bars 1 are secured by bolts 3'. The cross-head 2 may be an old or dlscarded one provided the faces 4 at the bottom of the grooves or guide ways are finished parallel and at the exact distance apart'that the corresponding faces on the cross-heads to bo finished are to be. The bars l are longitudinally slotted as at 5 to receive the bolts 3 for a purpose which will appear herein- The upper portions the portions projecting beyond the member Qare tapered as at 6 and'the inclined or converging edges 7 thereof are grooved longitudinally as at' 8, said grooves extending preferably the entire length of the tapered portion 6. Slid'ably mounted onthe edges 7 are a pair of members 9 which are tapered in the opposite direction from the taper of the-bars '1 and their innei' faces or edges are provided with tongues 10 which fit in the grooves 8.. The taper of the portion 6 and that of the members 9 "tire equal so that the outer edges 11" of the members 9 lie parallel at all times. It is obvious that the distance between the edges 11 may be nicely regulated by adjusting the relative positions of the members 9 on the member 1.-

, The upper or broad ends of the members of the bars 1, that is 45 ,I move downwardly on the portion 6 of the 9' are connected by a plate 12 and a pair] Having described my invention what I 65 relation to the bars 1.

conical portion 22 adapted to fit in a recess of bolts 18 extending through the plate into id members. A plate 12 is provided with longitudinal slots ll to receive the bolts 13 to permit movement of the members 9 toward or fromeach other. The members 1 and 9are preferably of the same thickness, but it is important that the inner faces 15 lie in the same plane. 7

.An adjusting screw 16 extends through a centrally disposed perforation 17 in the plate 12 and is threaded into the upper end of the bar 1, said bar being provided with a threaded bore 18 for this purpose. 1

19 indicates a collar on the screw 16 which bears against the upper face of the plate 12 and 20 indicates means on the upper end of the screw, such as a crank, for turning the same. By turning the crank 20 to the right the members 1 and 9 are moved longitudinally with relation to each other resulting in a spread of the members and corresponding widening of the device.

21 indicates a mandrel for centering the cross-head A, which is to be remetaled, with This'comprises a 23 in f the member 2," which recess when a cross-head is used comprises a socket for the endof the piston rod, and an oppositely extending conical portion 24 adapted to extend within the similar portion of the cross-head A. The portion 24.- is longer than the portion 23, thereby being greater'in diameter atthe base and forming a shoulder, 25 which rests upon the upper end of the member 2.

Inusing the device the mandrel 21 is placed in position on the member 2 and the cross -head A placed on the mandrel as shown in Fig. 1 with the upwardly extend- I ing adjustable portion of the bars 1 within the guide ways B. The cranks 20' are then turned until the members 1 and 9 are tightly wedged between the flanges C. In wedging the members in position the members 9 member, 1. However should the lower ends of the members 9 come in contact with the ',member 2 before the device is sufiiciently .tight the member 1 will be raised until the desired result is accomplished, the slots 5 permitting the upward movement thereof.

After the device is tightened or clamped in position the lower ends of the mold cavities are closed with a small portion of stiff clay and the molten metal is poured into the apertures between'th'e members 1 and 9 and the bottom of the guide ways B. As the inn'erfac'es of the members 1 and 9 are in the same plane the face of the metal will be perfectly smooth without planing and as the two members 1 are parallel the crosshead A will ,be ready to replace in the enmm as soon as the metal is cool.
